JEE MAIN - Chemistry (2018 - 16th April Morning Slot - No. 10)
When 9.65 ampere current was passed for 1.0 hour into nitrobenzene in acidic medium, the amount of p-aminophenol produced is :
9.81 g
10.9 g
98.1 g
109.0 g
Explanation

Moler mass of p$$-$$aminophenol
= 6 $$ \times $$ 12 + 7 + 14 + 16
= 109 gmol$$-$$1
Eq. weight (E) = $${W \over Q}$$ $$ \times $$ 96500
$$ \Rightarrow $$$$\,\,\,$$ W = $${{E\,Q} \over {96500}}$$
$$ \Rightarrow $$$$\,\,\,$$ W = $${{E\,I\,t} \over {96500}}$$
$$ \Rightarrow $$$$\,\,\,$$ W = $${{109} \over 4} \times {{9.65 \times 3600} \over {96500}}$$
$$ \Rightarrow $$$$\,\,\,$$ W = 9.81 gm
